Exploitability

CWE

KEV

CWE ID	Description
CWE-416	The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Attack-Flow Graph

Executive Summary

This is a use-after-free vulnerability in Chromecast within Google Chrome versions before 152.0.7977.65. A use-after-free occurs when a program continues to use a pointer after freeing the memory it points to. In this case, a remote attacker who had already compromised the renderer process could exploit this to execute arbitrary code outside the sandbox by tricking a user into visiting a specially crafted HTML page.

Impact Analysis

If you are using an affected version of Google Chrome, this vulnerability could allow an attacker who has already gained control of the renderer process to escape the sandbox and execute malicious code on your system. This could lead to unauthorized access, data theft, or installation of malware. Updating to the latest version of Chrome patches this issue.

Mitigation Strategies

Update Google Chrome to version 152.0.7977.65 or later to address the use after free vulnerability in Chromecast.
